Zac Efron's condition is critically seksi as he plays a doctor in the new trailer for Parkland! He can certainly give us a physical any day o' the week!

Zac plays the young attending physician on duty at the Parkland Memorial Hospital the day JFK was shot, and brought under his care. In addition, Parkland is where JFK's assassin, Lee Harvey Oswald, was sent after being shot himself, and where he also died just two days after JFK.

Parkland harkens back (and to the left) to that fateful November day in 1963, telling the tale of the Presidential assassination through the eyes of the lesser known but influential men and women who endured that awful day in Dallas.

We can't wait to see Zac and the rest of his stellar fellow cast members when this historical movie comes out on September 20th!
